Harris County Precinct 4 deputy constables arrived at a Spring home to serve a search warrant for child pornography and found a firefighter in bed with an underage boy, investigators said.

Chaise Green, 28, of Lafayette, La., faces three counts of possession of child pornography after deputies seized computers and storage drives with images and videos of young boys engaged in sex with adult men, court records show. A judge set $20,000 bail on each count for Green, who was being held Friday at the Harris County Jail.

Deputies with the Precinct 4 Constable's High Tech Crime Unit served search warrants Wednesday at two homes in Spring - one on Glenbranch Drive and another off Spring Stuebner, where Green lived with his fiancé, her mother and his fiancé's two boys, ages 8 and 4, said Sgt. Gary Spurger.

When officers arrived at the home, "We pulled him (Green) out of the bedroom and the 8-year-old boy was in his (Green's) bed," Spurger said. "The boy was wearing shorts, and Green was wearing shorts and a T-shirt. It just struck us as unusual that he would be in bed with the suspect."

It has not been determined whether Green had engaged in improper behavior with the boy, said Assistant Chief Tim Cannon, who heads the High Tech Crime Unit.

"In this circumstance, there wasn't anything improper going on that we know of," Cannon said. "This is a case where the guy lives with his fiancé, and they (family) all slept together in the same bed occasionally."

The boy's mother was at the home when the warrant was served but had stepped outside for a cigarette when officers entered the bedroom, according to investigators.

Questioned by investigators, Green admitted "to using those computers and storage devices to search for, download and view the images and videos of child pornography," according to a criminal complaint filed in the case.

Green is a former emergency medical technician and van driver at the Arcadian Ambulance Service in Lafayette, La., and also worked as a volunteer firefighter in South Montgomery County before he was fired about three months ago, Cannon said.
